Name the step of electrophoresis in which the separated bands of DNA are cut out from agarose gel and is extracted from a gel piece.

Explanation

To answer the question, we need to identify the specific step in the electrophoresis process where the separated bands of DNA are cut out from the agarose gel and extracted. Here’s the step-by-step solution:

### Step-by-Step Solution:

1. **Understanding Electrophoresis**: Electrophoresis is a technique used to separate DNA fragments based on their size. When DNA is subjected to an electric field in an agarose gel, the fragments migrate at different rates, leading to separation.

2. **Preparation of Agarose Gel**: Initially, DNA samples are loaded into wells of an agarose gel. The gel is then subjected to an electric current, causing the DNA fragments to move through the gel matrix.
